Smell Pittsburgh is a free iPhone app developed by Illah Nourbakhsh. It falls under the lifestyle category with a specific focus on weather. The app aims to engage Pittsburgh residents in tracking pollution odors across the region.

The main feature of Smell Pittsburgh is its ability to allow users to submit smell reports on a given date. These reports are then displayed on a map-view, showing the areas where odors have been frequently concentrated. By tracking these smell events, residents can identify areas with poor air quality and determine if they are upwind from those locations.

With Smell Pittsburgh, residents can actively participate in monitoring and addressing pollution issues in their community. The app provides a valuable tool for individuals to contribute to the improvement of air quality in Pittsburgh.
